Latest Metaplasticity Stories
Like a gardener who stakes some plants and weeds out others, the brain is constantly building networks of synapses, while pruning out redundant or unneeded synapses.
Nicolas G. Bazan, MD, Ph.D, Boyd Professor and Director of the Neuroscience Center of Excellence at LSU Health Sciences Center New Orleans, and David Stark, an MD/Ph.D student working in his lab, have discovered how a key chemical neurotransmitter that interacts with two receptors in the brain promotes either normal function or a disease process -- determining whether brain cells live or die.
A person who drinks too much alcohol may be able to perform complicated tasks, such as dancing, carrying on a conversation or even driving a car, but later have no memory of those escapades.
Have a tough time remembering where you put your keys, learning a new language or recalling names at a cocktail party?
Medical researchers have found a so-called "missing link" that explains the interaction between brain state and the neural triggers responsible for learning.
In the brain, many types of synaptic proteins are spatio-temporally regulated to maintain synaptic activity at a constant level. Here, the Japanese research group led by Professor Masaki Fukata
Scientists have uncovered a novel mechanism linking soluble amyloid ? protein with the synaptic injury and memory loss associated with Alzheimer's disease
U.S.-led research is providing strong support for the idea that one of the key functions of sleep is the consolidation of memories. University of Pennsylvania School of Medicine researchers say although sleep is thought to facilitate memory and learning, the molecular links between sleep and synaptic plasticity aren't well understood.
New research provides strong support for the idea that one of the key functions of sleep is the consolidation of memories. The study, published by Cell Press in the February 12th issue of the journal Neuron, provides fascinating insight into the cellular mechanisms that govern the sleep-dependent consolidation of experiences that occur while we are awake.
